[@hantuidola6648]

Thank you for information what about cooling tower operation?

[@sampatil-f8d]

I think colur coding for primary-secondary CHW system is wrong (3:03)

[@mohamedyasar5351]

Thank you for your information,i need more video about HVAC like troubleshooting in package , outdoor dx AHU ,pump, motor,more about electrical and isolation rooms and cooled rooms systems

[@zebralearnings]

Return and supply chilled water are not mixing in the header.

@@zebralearnings Thank you

[@BloominOnion1]

@@Dizzyofficial2166 He's not right. They do mix, and are supposed to mix, depending on fluctuations in the flow rates between primary loop vs secondary loop. Otherwise, the header pipe wouldn't exist!

00:02 Two types of pumps used in chiller plant: primary and secondary
00:29 Primary chilled water system uses only a primary pump.
01:10 Primary pump in HVAC system circulates chilled water from chiller to AHU.
01:45 Primary chilled water system less efficient than primary secondary system
02:16 Primary secondary chilled water system uses two pumps
02:49 Primary pump sends water to chiller for consistent flow
03:22 Primary and secondary pumps prevent water mixing in HVAC systems.
